Either you have a ram problem, or your hard drive is failing.
See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
For a laptop, or netbook, you must remove both its main battery and AC adapter before you do that.
For a brand name computer, see the Owner's or User's manual if you need to - how to remove or replace the ram is usually in that - it may already be in your installed programs. If you can't get into Windows, it may be on a disk that came with the computer, or you can go online and look at it or download it - it's in the downloads for your specific model.
Check your hard drive with the manufacturer's diagnostics.

Hard Drive Diagnostics Tools and Utilities
If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best compatibilty, on another computer if you need to.
If the hard drive itself tests okay, any data problems found can be fixed, one way or another.
If your hard drive is failing, if it can still be accessed, you can connect it to another working computer and copy files off of it that your don't want to lose to somewhere else - to a hard drive , or to CDs or DVDS, or to flash drives, etc. You don't need to be concerned about anything you can re-install if you have the disks for that, or can easily download from the web again. Don't bother trying to copy Windows files otherwise.
